Batch Nanotube Fabrication
For the first time ever, scientists in California have demonstrated large arrays of fully functional nanotubes. The structures have the ability to innovate, among other things, the display control circuit technology. The arrays that feature carbon nanotubes are more flexible than silicon, and more efficient at doing their jobs. The team used simple and easy methods of producing the arrays, which were derived from batches of carbon nanotubes that were impure. Scientists explain that today each pixel on the LCD screen of a computer is controlled by a number of transistors, which are generally made out of silicon, and fashioned into arrays. The latter are constructed inside vacuum chambers, at high temperatures, which makes the end product very simple. The solution-processing technique that results in the new nanotubes takes place at room temperature, which means production costs go down dramatically.
